There are two reasons for that: 1) She was an individualist who was explicitly opposed to all forms of collectivism. That upsets the Poalers who hate international socialism, but are gung ho for the national variety. She'd correctly point out that either is going to steal your stuff and get you killed in a war, one just does it for your local dictator instead of a million petty dictators on every streetcorner. 2) She was ethnically Jewish. Though an avowed atheist who fled the USSR for the capitalist mecca of 1920s seems a far cry from the usual tropes. Particularly given her decades of railing against religion, government, and alphabets. Personally I'd most strongly criticize her for her romantic choices, but I doubt Poal would much care about that.
